DETAILED DESCRIPTION
[0027] The core of the present invention is to provide a thermal integrated valve group for a vulcanizer, which has a compact structure, few leakage points and occupies a small space.
[0028] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0029] Please refer to Figure 1 and Figure 2 , Figure 1 This is a structural schematic diagram of a specific implementation of the thermal integrated valve group for a vulcanizer provided by the present invention; Figure 2 This is a schematic structural diagram of a specific implementation of the flow channel module provided by the present invention.
[0030] The vulcanizer thermal integrated valve group provided in the specific embodiment of the present invention includes a flow channel module 1, a feed valve, a discharge valve 2 and a regulating cut-off valve 3 for adjusting the flow of a medium. The flow channel module 1 is provided with a feed port 11, a discharge port 12, a first channel port 13 and a second channel port 14. The first channel port 13 is connected to the feed port 11 through a channel in the flow channel module 1, and the second channel port 14 is connected to the discharge port 12 through a channel in the flow channel module 1. The outlet of the feed valve is connected to the feed port 11 through a pipeline, and the discharge port 12 is connected to the inlet of the discharge valve 2 through a pipeline. The regulating cut-off valve 3 is installed on the flow channel module 1, and the inlet of the regulating cut-off valve 3 is connected to the first channel port 13, and the outlet of the regulating cut-off valve 3 is connected to the second channel port 14; the regulating cut-off valve 3 is driven by hydraulic pressure.
[0031] When in use, the feed valve and the discharge valve 2 are opened, and the material flows into the flow channel module 1 from the feed port 11 of the flow channel module 1 along the pipeline, and then flows through the first channel port 13, the regulating cut-off valve 3 and the second channel port 14 in sequence, and then flows out from the discharge port 12 on the flow channel module 1. In this process, the flow rate of the material can be adjusted and the material can be cut off by adjusting the cut-off valve 3; the regulating cut-off valve 3 is integrated into the flow channel module 1, and a channel for connecting the feed valve and the discharge valve 2 is set in the flow channel module 1, which can reduce the bending pipeline, reduce the leakage point, reduce the occupied space of each pipeline, and improve the integration of the valve group; in addition, the regulating cut-off valve 3 adopts a hydraulic drive mode, so that the drive station can be controlled by only setting up a drive station instead of the original need to set up a pneumatic drive station and a hydraulic drive station, which saves costs and reduces the occupied space. Therefore, the thermal integrated valve group of the vulcanizer provided by the present invention has a compact structure, few leakage points, low cost, and small occupied space.
[0032] Furthermore, in actual production applications, there are usually multiple feed pipelines and discharge pipelines to achieve mixing or distribution of different materials. One feed pipeline may need to be connected to multiple discharge pipelines, or multiple feed pipelines need to be connected to one discharge pipeline. There are many situations. In order to facilitate connection and reduce bending pipes, leakage points and occupied space, in a specific embodiment, the vulcanizer thermal integrated valve group provided by the present invention can be provided with multiple feed ports 11 and several discharge ports 12 on the flow channel module 1, and the number of feed ports 11 is greater than the number of discharge ports 12, and the flow channel module 1 A plurality of first channel openings 13 corresponding to the feed ports 11 and a plurality of second channel openings 14 corresponding to the first channel openings 13 are also provided. The first channel openings 13 correspond to the feed ports 11 one by one, and each first channel opening 13 is connected to a corresponding feed port 11, and the first channel openings 13 are not connected to each other. The second channel openings 14 correspond to the first channel openings 13 one by one, and each group of corresponding first channel openings 13 and second channel openings 14 are connected through an adjusting cut-off valve 3. A connecting flow channel connecting the second channel openings 14 is also provided in the flow channel module 1.
[0033] When in use, the material flows into the flow channel module 1 along each feed pipeline and from each feed port 11, and then flows through the corresponding first channel port 13, the adjusting cut-off valve 3 and the second channel port 14 in turn to enter the connecting flow channel and merge, and finally flows out from the discharge port 12 on the flow channel module 1. In this process, each feed pipeline can transport different materials respectively, and the flow rate of the material flowing into each feed port 11 can be adjusted by adjusting the cut-off valve 3, so as to meet various mixing requirements, and at the same time, the use of bent pipes can be minimized, with high integration, few leakage points and small space occupation.
[0034] In another specific embodiment, the vulcanizer thermal integrated valve group provided by the present invention can be provided with a plurality of feed ports 11 and a plurality of discharge ports 12 on the flow channel module 1, and the number of the discharge ports 12 is greater than the feed port 11, and at the same time, the flow channel module 1 is also provided with a plurality of second channel ports 14 corresponding to each discharge port 12 and a plurality of first channel ports 13 corresponding to each second channel port 14, the second channel ports correspond one-to-one to the discharge ports 12, and each second channel port 14 is connected to a corresponding discharge port 12, the second channel ports 14 are not connected, the first channel ports 13 correspond one-to-one to the second channel ports 14, and each group of corresponding first channel ports 13 and second channel ports 14 are connected through an adjusting cut-off valve 3, and a connecting flow channel connecting the first channel ports 13 is also provided in the flow channel module 1.
[0035] When in use, the material flows into the flow channel module 1 from the feed port 11 along the feed pipeline, converges into the connecting flow channel, is then diverted through the first channel port 13, and then flows through the corresponding regulating cut-off valve 3 and the second channel port 14 in sequence before flowing out from the corresponding discharge port 12. In this process, the flow rate of the material flowing out of each discharge port 12 can be adjusted by adjusting the cut-off valve 3 to meet different feeding requirements, and at the same time, the flow rate of the material flowing into each feed port 11 can be adjusted by adjusting the cut-off valve 3.
[0036] The specific embodiment of the present invention provides a vulcanizer thermal integrated valve group, the number of flow channel modules 1, the number of feed ports 11 and discharge ports 12 on the flow channel module 1, and the number of regulating cut-off valves 3 installed can all be selected and set according to actual use requirements, and this application does not impose specific restrictions on this.
[0037] On the basis of the above-mentioned specific embodiments, the vulcanizer thermal integrated valve group provided in the specific embodiment of the present invention can be configured as a rectangular module for the convenience of connection and to make the structure more compact, the feed port 11 is arranged at the front end face of the flow channel module 1, the discharge port 12 is arranged at the rear end face of the flow channel module 1, the first channel port 13 and the second channel port 14 are both arranged at the upper end face of the flow channel module 1, and the regulating cut-off valve 3 is installed on the upper end face of the flow channel module 1; in addition, for the convenience of installation, a support frame 4 can be provided on the lower end face of the flow channel module 1.
[0038] Please refer to Figure 3 , Figure 3 This is a schematic structural diagram of a specific implementation of the filter valve provided by the present invention.
[0039] Furthermore, in the thermal integrated valve group of the vulcanizer provided in the specific embodiment of the present invention, a filter valve 6 may be installed on the pipeline connecting the discharge port 12 and the discharge valve 2 to filter impurities in the material.
[0040] Specifically, the filter valve 6 includes a filter valve body 61 having an inner channel, and an inlet flange 62 and an outlet flange 63 detachably mounted on the left and right ends of the filter valve body 61, respectively. The inlet flange 62 is mounted at the inlet end of the inner channel, and the outlet flange 63 is mounted at the outlet end of the inner channel. Both the inlet flange 62 and the outlet flange 63 are detachably connected to the filter valve body 61, and both the inlet flange 62 and the outlet flange 63 are provided with through holes communicating with the inner channel. In addition, a filter screen 64 for filtering impurities is provided between the filter valve body 61 and the outlet flange 63, and a sewage outlet 65 is provided at the lower end of the filter valve body 61. When in use, the filter valve body 61 is installed on the pipeline through the inlet flange 62 and the outlet flange 63 at both ends, and it is ensured that the flow direction of the medium fluid is from the inlet end of the inner channel to the outlet end, and the sewage outlet 65 is vertically downward. When the fluid passes through the inner channel and flows out from the outlet end of the inner channel, the impurities in the fluid will be filtered by the filter screen 64 and directly fall to the sewage outlet 65. There are fewer impurities attached to the filter screen 64, so the filter screen 64 is cleaned less frequently, and when the filter screen 64 needs to be cleaned, it only needs to remove the outlet flange 63, and the filter screen 64 can be folded down for cleaning or replacement, which is simple and convenient.
[0041] Furthermore, to facilitate the installation of the filter 64, a filter groove can be processed on the end face of the filter valve body 61 for connecting to the outlet flange 63, and the edge of the filter 64 can be installed in the filter groove; of course, the filter groove can also be opened on the end face of the outlet flange 63 for connecting to the filter valve body 61, which is also within the protection scope of the present invention.
[0042] Please refer to Figure 4 , Figure 4 The figure is a schematic structural diagram of a specific implementation mode of the wafer-type check valve provided by the present invention.
[0043] The vulcanizer thermal integrated valve group provided in the specific embodiment of the present invention can also be installed with a clamp-type check valve 5 on the pipeline connecting the feed valve and the feed port 11 and / or the pipeline connecting the discharge port 12 and the discharge valve 2, which can prevent backflow and series connection; the clamp-type check valve 5 can specifically include two check flanges 51 and a check valve body 52 with a check valve cavity, one end of the check valve cavity is the inlet end, and the other end is the outlet end, the two check flanges 51 are respectively installed at the two ends of the check valve body 52, and both are detachably connected to the check valve body 52, a through hole connected to the check valve cavity is opened in the middle of the check flange 51, a return spring 53 and a valve plate 54 capable of closing the inlet of the check valve cavity are installed in the check valve cavity, and the valve plate 54 is installed at the inlet end of the check valve cavity.
[0044] When in use, the check flanges 51 at both ends of the check valve body 52 are installed on the pipeline, which is simple and convenient. When no medium flows in, the valve plate 54 closes the entrance of the check valve chamber under the action of the return spring 53. When the flow pressure of the medium flowing into the check valve chamber entrance is greater than the check valve chamber outlet, the valve plate 54 is pushed open and the pipeline channel is connected. When the medium flow pressure decreases, the valve plate 54 closes the check valve chamber entrance again under the action of the return spring 53, thereby preventing backflow and series connection. Since the two ends of the check valve body 52 are detachably connected to the check flange 51, when a problem occurs, the check flange 51 can be disassembled from the check valve body 52, which is convenient for maintenance.
[0045] Please refer to Figure 5 , Figure 5 It is a structural schematic diagram of a specific implementation mode of the regulating cut-off valve 3 provided by the present invention.
[0046] On the basis of the above-mentioned specific embodiments, the vulcanizer thermal integrated valve group provided in the specific embodiment of the present invention, the regulating cut-off valve 3 can specifically include a first valve body 31 with a first valve cavity, the inlet and outlet of the regulating cut-off valve are connected through the first valve cavity, and both are arranged at the lower end of the first valve body 31, the upper end of the first valve body 31 is provided with a first hydraulic chamber 32, the first hydraulic chamber 32 is provided with a spring 35, a push plate 36 and a first valve stem 33, the upper end of the first valve stem 33 is fixedly connected with the push plate 36, the lower end of the first valve stem 33 passes through the first valve cavity, and the lower end is provided with a plug 34 for blocking the outlet, and the plug 34 is a conical plug 34, the push plate 36 is slidably connected with the first hydraulic chamber 32, and the first hydraulic chamber 32 is divided into an upper chamber and a lower chamber, and the first valve body 31 is provided with an oil inlet and an exhaust port respectively connected to the upper chamber and the lower chamber.
[0047] The inflow and outflow of hydraulic oil can push the push plate 36 to drive the first valve stem 33 to move up and down, and the first valve stem 33 drives the plug 34 to move up and down to open or close the outlet, thereby realizing the opening and closing action of the regulating cut-off valve 3; the integrated valve group and the vulcanizer are both hydraulically driven, so only one drive station is required, and the hydraulic drive has a small size and a large driving force, which can save space; in addition, since the plug 34 is a conical plug 34, when the plug 34 moves up and down, the channel between the plug 34 and the outlet will gradually increase or decrease, so the flow rate of the regulating cut-off valve 3 can be gradually increased or decreased, so that the regulating cut-off valve 3 has the functions of opening and closing and regulating the medium flow rate. When installed on the pipeline for use, there is no need to adjust the valve, which can save costs.
[0048] The oil inlet and the exhaust port are set at different positions on the first valve body 31, and the control methods of the regulating cut-off valve 3 are different.

At the same time, the first valve stem 33 drives the plug 34 to move upward to gradually open the outlet, and the valve gradually opens; when the valve needs to be closed or the flow rate needs to be reduced, the oil flows out from the lower chamber through the oil inlet in the opposite direction, and the push plate 36 moves downward under the action of the spring 35, and the external gas enters the upper chamber from the exhaust port. At the same time, the push plate 36 drives the first valve stem 33 and the plug 34 to move downward to gradually close the outlet, and the valve gradually closes.
[0049] When the oil inlet is connected to the upper chamber, the oil inlet can be set at the top of the first valve body 31, the spring 35 is installed between the push plate 36 and the bottom wall of the first hydraulic chamber 32, and the exhaust port can be set on the side wall of the first valve body 31 and connected to the lower chamber; when the oil enters the upper chamber from the oil inlet, the push plate 36 is pushed to drive the first valve stem 33 to move downward, compressing the spring 35, and the gas in the lower chamber is discharged from the exhaust port. At the same time, the first valve stem 33 drives the plug 34 to move downward to gradually close the outlet, and the valve gradually closes; when the oil flows out from the upper chamber through the oil inlet in the opposite direction, the push plate 36 moves upward under the action of the spring 35, and the outside gas enters the lower chamber from the exhaust port. At the same time, the push plate 36 drives the first valve stem 33 and the plug 34 to move upward to gradually open the outlet, and the valve gradually opens.
[0050] Please refer to Figure 6 , Figure 6 The figure is a schematic structural diagram of a specific implementation mode of the triangular ball valve provided by the present invention.
[0051] Furthermore, in the specific embodiment of the present invention, the feed valve and the discharge valve 2 of the vulcanizer thermal integrated valve group can both be triangular ball valves, which have a simple and compact structure, reliable sealing, and are easy to use. Of course, the feed valve and the discharge valve 2 can also use other types of valves, as long as they can realize the opening and closing of the pipeline, they are all within the protection scope of the present invention.
[0052] Specifically, the triangular ball valve may include a second valve body 21 and two flanges 22 detachably mounted on the left and right ends of the second valve body 21, and when in use, the triangular ball valve can be connected to a pipeline through the flanges 22, the second valve body 21 has a second valve cavity that runs transversely therethrough, the middle portions of the two flanges 22 are provided with through holes that communicate with the second valve cavity, a spherical valve core 23 is mounted in the second valve cavity, a transversely running channel is opened on the spherical valve core 23, the through holes on the two flanges 22 can be connected through the channel, a second valve stem 25 connected to the spherical valve core 23 is mounted on the side wall of the second valve body 21, and the second valve stem 25 is connected to the spherical valve core 23 through the second valve cavity. The valve stem 25 can rotate the spherical valve core 23 to realize the on and off of the medium flow pipeline. Annular seals 24 are installed at both ends of the second valve chamber. The annular seal 24 is located between the flange 22 and the spherical valve core 23, and the two sides of the annular seal 24 are tightly fitted with the end face of the flange 22 and the outer wall of the spherical valve core 23 respectively; the left and right ends of the ball valve and the pipeline connection are set as detachable flanges 22, which have a simple structure and are easy to assemble. When there is a problem with the annular seal 24, the flange 22 can be directly removed, and the annular seal 24 can be reinforced or replaced without replacing the ball valve as a whole, which can save costs.
